CROSS REFERENCE TO RELATED APPLICATION BACKGROUND OF THE INVENTION

1. Technical Field

The present invention relates to an apparatus for removing acontaminated material included in high high viscosity oil droplet andfine dust.

2. Description of the Related Art

Generally, as technologies fields and including an air contaminatedmaterial, a technology for processing a particulate air contaminatedmaterial, an electrostatic precipitator, a filter dust collector, or thelike, has been used. Furthermore, a technology for processing a gaseousair contaminated material, an absorption method, an adsorption method, acatalytic oxidizer, or the like, has been used. However, in the case ofprocessing the exhaust gas containing a large amount of high viscosityoil droplet, fine dust, and a gaseous air contaminated material, at thetime of applying a general processing technology, the processingefficiency decrease and a maintenance cost increases.

Particularly, at the time of using a general processing apparatus as anapparatus for processing the exhaust gas generated at the time ofbiomass burning and containing fine dust and oil droplet including alarge amount of pyroligneous liquor generated in carbonization process,such as a charcoal kiln for charcoal production or a charcoal kiln forfomentation, processing efficiency decreases and a processing costincreases. The reason that the processing efficiency decreases and theprocessing cost increases is that the high viscosity oil droplet isadhered to a surface of the electrostatic precipitator, such that it isnot easily separated or the high viscosity oil droplet closes afiltering pore of a filter cloth of the filter dust collector toincrease differential pressure, such that it is not processed orseparated, whereby the electrostatic precipitator or the filter dustcollector should be replaced.

In addition, at the time of use of a general air contaminated materialprocessing apparatus as an apparatus for processing the exhaust gascontaining oil droplet generated in a process of roasting meat and finedust or an apparatus for processing oil vapor and exhaust gas generatedin a drying process, or the like, of a food processing factory andcontaining high viscosity and high temperature oil droplet and finedust, it is difficult to process the exhaust gas containing the oildroplet generated in a process of roasting meat and the fine dust andthe oil vapor and the exhaust gas containing the high temperature oildroplet and the fine dust. Further, even in an apparatus for processingthe exhaust gas discharged from an industrial facility and containing alarge amount oil droplet and oil vapor, an improved processingtechnology has been demanded.

In order to solve these problems, various processing systems forremoving high viscosity oil droplet and fine dust in the exhaust gas ofa kiln for charcoal production and a charcoal kiln for fomentation, theexhaust gas of a meat roasting restaurant, the oil vapor generated in adrying process of a food processing factory, and the exhaust gasgenerated in an industrial facility and containing high viscosity oildroplet and fine dust have been developed, and a technology forimproving dust removing efficiency and recovering and recycling energyfrom high temperature exhaust gas has been required.

Terms “apparatus”, “units”, “assembly”, and “part” forcomponents used in the following description are used only in order toeasily make a specification. Therefore, the above-mentioned terms do nothave meanings or roles that distinguish from each other in themselves.

Furthermore, This present invention is supported by Korea Ministry ofEnvironment as “The Eco-Innovation 21 project(401-112-018)

FIGS. 1A and 1B are block diagrams showing a configuration of an energyrecycling type dust removing processing system for removing acontaminated material in high temperature contaminated gas according toan exemplary embodiment of the present document. As shown in FIGS. 1Aand 1B, the energy recycling type dust removing processing system forremoving a contaminated material in high temperature contaminated gasaccording to the exemplary embodiment of the present document may beconfigured to include a collecting duct 20 collecting a high temperaturecontaminated gas generated from a high temperature contaminationgeneration source 10 (a charcoal kiln, a meat roasting restaurant, afood processing factory, or the like) and including high temperaturedust; an energy recovering and inertial impact type dust removing unit30 including an energy recovering apparatus 31, an inertial impact typedust removing apparatus 33, and an inertial impact type energyrecovering and dust removing assembly 35; a pyroligneous liquor or oilvapor recovering can 40; an in-flight adsorption apparatus 50; an opendamper 51; a micro dust removing apparatus 60; an unburned materialreturning apparatus 70; and a self flow rate controlling blowingapparatus 80.

Here, the high temperature contamination generation source 10 means acontamination generation source discharging a high temperature gas, suchas the charcoal kiln for producing charcoal, the meat roastingrestaurant, an incineration plant, or the like.

The collecting duct 20 serves to collect the high temperaturecontaminated gas generated in the high temperature contamination source10 and including the high temperature dust. As described above, the hightemperature contaminated gas collected in the collecting duct 20 ismoved to the energy recovering and inertial impact type dust removingunit 30.

The energy recovering and inertial impact type dust removing unit 30serves to recover the energy of the high temperature contaminated gas toconvert the high temperature contaminated gas into middle-lowtemperature contaminated gas (changes cold water (refrigerant) into hotwater heat generated at this time) and remove coarse dust in thecontaminated gas. The energy recovering and inertial impact type dustremoving unit 30 may include the energy recovering apparatus 31, theinertial impact type dust removing apparatus 33, and the inertial impacttype energy recovering and dust removing assembly 35 (an integral type).An example of the energy recovering apparatus 31 will be described withreference to FIG. 3, and an example of the inertial impact type energyrecovering and dust removing assembly 35 will be described withreference to FIGS. 4A and 4B.

The energy obtained from the energy recovering and inertial impact typedust removing unit 30 is recycled in an energy recycling system 100. Theenergy recycling system 100 will be described with reference to FIG. 2.

The in-flight adsorption apparatus 50 serves to remove fine dust in thecontaminated gas in which the coarse dust is removed in the energyrecovering and inertial impact type dust removing unit 30 and mayinclude a cyclone apparatus and a chamber 300. The cyclone apparatus,which is an apparatus removing dust using centrifugal force, movesparticulate matters (dust) in a fluid introduced in a tangent line of acylindrical housing to a wall surface by the centrifugal force andallows the dust moved to the wall surface to drop downwardly and beheaped in a hopper, thereby removing the fine dust. Meanwhile, thechamber will be described in more detail with reference to FIGS. 5 to 9.

When an air inlet is closed in order to block the supply of oxygen in acarbonization process as in a charcoal kiln, a generated flow ratebecomes small. Therefore, in order to supply a constant flow rate to asubsequent processing apparatus, the open damper 51 is opened to supplya constant flow rate to a subsequent processing apparatus. That is, aprocessed flow rate of the micro dust removing apparatus 60 is allowedto be constant, such that a processing speed is maintained to beconstant, thereby increasing the processing efficiency of the micro dustremoving apparatus 60.

The micro dust removing apparatus 60 serves to remove micro dust in thecontaminated air from which the fine dust is removed by the chamber 300.As the micro dust removing apparatus 60, at least one of a middleperformance high temperature type adsorption filter 61, an electrostaticprecipitator (ESP) 63, a bag filter dust collector 65, and anelectrostatic cyclone 67 may be used.

The unburned material reburning apparatus 70 includes a sensorconfigured to sense carbon monoxide (CO), hydrocarbon (HC), or the like,which is a combustible material. Therefore, the unburned materialreburning apparatus 70 ignites and burns CO or HC using auxiliary fuelwhen it is sensed that concentration of CO or HC is a predeterminedlevel or more, thereby converting CO or HC into carbon dioxide or waterwhich is a harmless material. The unburned material reburning apparatus70 may be installed at the front end of the open damper 51 in the casethat the pyroligneous liquor is recovered or be installed between thecollecting duct 20 and the energy recovering and inertial impact typedust removing unit 30 in the case that the pyroligneous liquor is notrecovered.

The self flow rate controlling blowing apparatus 80 opens the opendamper 51 in the case that a small amount of flow rate is introduced,such that a constant flow rate is maintained to hold efficiency of themicro dust removing apparatus 60 to be constant.

Next, a configuration of the energy recycling system 100 will bedescribed in more detail with reference to FIG. 2.

FIG. 2 is a block diagram of an energy recycling system included in theenergy recycling type dust removing processing system for removing acontaminated material in high temperature contaminated gas according tothe exemplary embodiment of the present document.

As shown in FIG. 2, the energy recycling system 100 may include a hotwater tank 102 storing hot water discharged from the energy recoveringand inertial impact type dust removing unit 30 therein, an auxiliaryburner 103-1 and a solar collector 103-2, which are auxiliary energyunits for heating the hot water tank, an absorption type coolingapparatus 107-1 performing a cooling function using the hot water of thehot water tank 102, a stirling power generator 109-1 generating powerusing the hot water of the hot water tank 102, a hot air heater 105-1performing a hot air heating function using the hot water of the hotwater tank 102, and a heating system 105-2 using the hot water.

Indoor cooling 107-2 may be performed by the absorption type coolingapparatus 107-1, and power generation 109-2 may be performed by thestirling power generator 109-1.

Next, structures of the energy recovering apparatus (a heat pipe) 31,the inertial impact type dust removing apparatus 33, the inertial impacttype energy recovering and dust removing assembly 35, and the chamberincluded in the energy recovering and inertial impact type dust removingunit 30 used in the energy recycling type dust removing processingsystem for removing a contaminated material in high temperaturecontaminated gas will be described in more detail with reference toFIGS. 3A to 9.

FIG. 3A is a diagram showing an example of a heat pipe (an energyrecovering apparatus) used in the energy recycling type dust removingprocessing system for removing a contaminated material in hightemperature contaminated gas according to the exemplary embodiment ofthe present document. As shown in FIG. 3A, the heat pipe 31 may includea plurality of first heat pipes 31-1 arranged in a first direction in aframe and a plurality of second heat pipes 31-2 arranged in a seconddirection perpendicular to the first direction. The high temperaturecontaminated gas generated in the contamination generation source 10passes between the first and second heat pipes 31-1 and 31-2, such thatheat of the high temperature contaminated gas is conducted to the firstand second heat pipes. Therefore, temperatures of the first and secondheat pipes 31-1 and 31-2 rise, such that the high temperaturecontaminated gas is converted into middle-low temperature contaminatedgas. The cold water introduced into an upper or horizontal separationcan is converted into hot water by the heat conducted to the heat pipe31.

The energy recovering and inertial impact type dust removing unit inwhich the heat pipe shown in FIG. 3A is used will be described withreference to FIG. 3B.

As shown in FIG. 3B, the energy recovering and inertial impact type dustremoving unit 30 may include a first inertial impact apparatus 33-1installed at the front end, a second inertial impact apparatus 33-2installed at the rear end, and a plurality of heat pipes 31 installed ata central portion.

The first inertial impact apparatus 33-1 serves to remove the coarsedust in the high temperature exhaust gas collected in and introducedfrom the collecting duct 20 at the front end by an inertial impactphenomenon.

The plurality of heat pipes 31 increase in temperature due to the heatof the high temperature exhaust gas, as described above with referenceto FIG. 3A. In this case, a temperature of water flowing (from A to B)through a waterway disposed at an upper portion of the energy recoveringand inertial impact type dust removing unit 30 rises, such that the coldwater is converted into the hot water and then discharged.

Meanwhile, the second inertial impact apparatus 33-2 having the sameform as that of the first inertial impact apparatus 33-1 is installed atthe rear end of the plurality of heat pipes 31 to remove the coarse dustonce again, thereby making it possible to increase a dust removing rate.

In addition, as shown in FIG. 3B, a porous plate 41 for recovering thepyroligneous liquor is installed at a lower end portion, and thepyroligneous liquor passing through the porous plate 41 is recovered bythe recovering can (not shown) installed at the lower end portion.

Next, the energy recovering and inertial impact type dust removing unitusing the inertial impact type energy recovering and dust removingassembly 35 used in the energy recycling type dust removing processingsystem for removing a contaminated material in high temperaturecontaminated gas according to the exemplary embodiment of the presentdocument will be described in detail with reference to FIGS. 4A and 4B.

FIG. 4A is a diagram showing an example of an inertial impact typeenergy recovering and dust removing assembly used in the energyrecycling type dust removing processing system for removing acontaminated material in high temperature contaminated gas according tothe exemplary embodiment of the present document.

As shown in FIG. 4A, the inertial impact type energy recovering and dustremoving assembly 35 (an integral type) may include a first blade 35-1inclined with respect to a flow of the high temperature contaminated gasby a predetermined angle to thereby be inclined with respect to adirection of a wind of the high temperature contaminated gas by apredetermined angle, a second blade 35-2 extended from the first blade35-1 while having a bending angle, and a heat pipe 36 formed at aconnection point between the first and second blades 35-1 and 35-2. Thecold water may be converted into the hot water by the heat pipe 36 andthen discharged.

Meanwhile, a pair of first blocking blades 35-3 is installed at theconnection point between the first and second blades 35-1 and 35-2. Thedust impacts the pair of first blocking blades 35-3, such that it isremoved by gravity.

In addition, a second blocking blade 35-4 is installed at a rear endportion of the second blade 35-2 to remove the dust once again.

The inertial impact type energy recovering and dust removing assemblymanufactured as described above may simultaneously perform the dustremoval and the energy recycling.

The energy recovering and inertial impact type dust removing unit 30 inwhich the inertial impact type energy recovering and dust removingassembly of FIG. 4A is used will be described with reference to FIG. 4B.The energy recovering and inertial impact type dust removing unit 30shown in FIG. 4B has substantially the same configuration as that of theenergy recovering and inertial impact type dust removing unit shown inFIG. 3B. Therefore, a description thereof will be omitted. Unlike theenergy recovering and inertial impact type dust removing unit shown inFIG. 3B, in the energy recovering and inertial impact type dust removingunit shown in FIG. 4B, the inertial impact type energy recovering anddust removing assembly 35 shown in FIG. 4A is installed at the centerand energy from the high temperature contaminated gas is transferred toa waterway disposed at an upper portion through a heat pipe 36 disposedat the center of the inertial impact type energy recovering and dustremoving assembly. Therefore, cold water supplied to the waterwaydisposed at the upper portion is converted into hot water, such that thehot water is discharged.

In addition, an inertial impact phenomenon is generated in each blade ofthe inertial impact type energy recovering and dust removing assembly35, such that the coarse dust included in the high temperaturecontaminated gas is removed.

FIG. 4C shows an example in which the air-cooling system is applies. Incase that the heat transmitted from the heat pipe 31 needs not to beused and the freeze and burst is available, the fan 37 is installed inthe upper portion as shown in the FIG. 4C. Accordingly, the heat pipe 31is heated by the contaminated air, the fan operates to cooling the heatpipe 31.

FIG. 5 is a diagram showing a first embodiment of a chamber 300 used inan in-flight adsorption apparatus in the energy recycling type dustremoving processing system for removing a contaminated material in hightemperature contaminated gas according to the exemplary embodiment ofthe present document.

As shown in FIG. 5, first partition wails 321 extended from sidewallsand second partition walls 323 extended from a central column 352 arealternately installed in a housing 310 to form a zigzag channel. Thischannel is connected to a first duct 311 and a second duct 313, suchthat exhaust gas introduced from the first duct 311 forms a zigzag aircurrent along the channel. As shown in FIG. 5, the first and secondpartition walls 321 and 323 are installed to be inclined at a downwardacute angle with respect to a horizontal direction of the housing 310,such that contaminated dust in which the contaminated material describedabove may fall down by gravity.

Meanwhile, a bottom surface of the housing 310 is provided with anadsorbent discharging unit 330. The adsorbent discharging unit 330 is anapparatus discharging an adsorbent adsorbing exhaust gas and generatingan impact effect to simultaneously coarsen fine dust to the zigzagchannel. As the adsorbent, activated carbon or zeolite may be used. Whenthis adsorbent is introduced into the zigzag channel formed by thepartition walls 321 and 323, it flows together with the exhaust gasalong an air current of the exhaust gas in the zigzag channel to collectthe contaminated material (gas and fine dust) included in the exhaustgas. When the contaminated dust becomes sufficiently heavy (that is,when the fine dust is coarsened), it falls on surfaces of the partitionwalls 321, 323. The dust falling as described above descends toward thebottom surface of the housing 310 due to the gravity, such that it iscollected in a contaminated dust receiving part 340 through an outlet327. In addition, the contaminated dust still present on the surfaces ofthe partition walls 321, 323 may fall to the contaminated dust receivingpart 340 via an impact apparatus 380.

Meanwhile, an inertial impact apparatus 350 having a secondary cleaningfunction may be configured to have three sub-filters 351, 353 354. Thefine dust of the primarily cleaned air is removed through the inertialimpact apparatus 350, such that further cleaned air may be discharged tothe second duct 313.

In addition, the chamber 300 may further include an inducing fan 360installed in order to induce a portion of an air current discharged fromthe second duct 313 to the adsorbent discharging unit 330. Therefore,the adsorbent may be easily introduced into the zigzag channel.

Next, shapes of the partition walls used to form the zigzag channel willbe described in more detail with reference to FIG. 6.

FIG. 6 is a perspective view of a partition wall used in the firstembodiment of the chamber. As shown in FIG. 6, a partition wall moduleused for the first and second partition walls 321 and 323 has generallya square shape and a cross section bent in an arc shape. The partitionwall module has a shape similar to that of a traditional kite. Thepartition wall module is formed as described above, such that thefalling contaminated dust may descend.

Next, the impact apparatus will be schematically described withreference to FIGS. 7 and 8.

FIG. 7 is a diagram describing an example of an impact apparatus used inthe first embodiment of the chamber; and FIG. 8 is a diagram describinganother example of an impact apparatus used in the first embodiment ofthe chamber. The impact apparatus 330 is an apparatus applying impact tothe housing 310 in order to remove the contaminated material heaped onthe surfaces of the partition walls 321, 323. According to the exampleshown in FIG. 7, motors 381 for applying the impact are installed atboth sides of the housing 310 and buffering parts 383 are installed atupper and lower ends of the housing 310. In addition, according toanother example shown in FIG. 8, in the impact apparatus 380, an impactweight 381′ is disposed at a central lower portion and a buffering part383′ for buffering impact in the case that the impact is applied to thehousing 310 by the impact weight 381′ is installed at a ceiling part ofthe housing 310 on the same line as the impact weight 381′.

The chamber according to the exemplary embodiment of the presentdocument includes the impact apparatus as described above, such that thecontaminated dust adsorbed with the contaminated material of the exhaustgas is not present on the partition walls, but is collected downwardly.Therefore, maintenance may be easily made.

Next, a second embodiment of the chamber according to the exemplaryembodiment of the present document will be described with reference toFIG. 9. A description of portions of the second embodiment of thechamber that are the same as those of the first embodiment of thechamber described above will be omitted for simplification.

FIG. 9 is a cross-sectional view of the second embodiment of thechamber. As shown in FIG. 9, in the second embodiment of the chamber 300according to the exemplary embodiment of the present document, theplurality of partition walls 321′ are attached to the bottom surface andthe ceiling surface of the housing 310 to form a zigzag channel, suchthat a vertical type zigzag channel is formed unlike the firstembodiment of the chamber described above. In addition, one end of thevertical type zigzag channel formed by the plurality of partition walls321′ is installed with a porous roller 329. The porous roller 329 servesto prevent air current from being divided in the contaminated dustreceiving part 340 to allow the adsorbent to be adsorbed well to thecontaminated dust and transfer the heavy contaminated dust to thecontaminated dust receiving part 340, simultaneously with serving totransmit the contaminated dust to the contaminated dust receiving part340.

According to a configuration of the second embodiment of the chamber300, the contaminated dust is not attached on the surfaces of thepartition walls 321, 323.

According to the exemplary embodiment of the present document having theabove-mentioned configuration, the dust, which is a particulate aircontaminated material in high temperature exhaust gas such as exhaustgas of a kiln for charcoal production and a charcoal kiln forfomentation, exhaust gas of a meat roasting restaurant, oil vaporgenerated in a drying process of a food processing factory, or the like,may be cleaned, and energy is recovered and recycled from the hightemperature exhaust gas, thereby making it possible to improve energyefficiency.

In addition, according to the exemplary embodiment of the presentdocument, coarse dust such as oil droplet, or the like, is first removedthrough the inertial impact type dust removing apparatus, such thatthere is an advantage in view of maintenance in that a dust collectingload of a subsequent micro dust removing apparatus is minimized anddurability of the entire system may be increased.

Further, the channel of the chamber in the in-flight adsorptionapparatus is formed in the zigzag shape to secure a residence time inwhich the contaminated material may be adsorbed to the adsorbent,thereby making it possible to improve removal efficiency of particulatematters and gaseous air contaminated materials.

According to the energy recycling type dust removing processing systemfor removing a contaminated material in high temperature contaminatedgas and the inertial impact type energy recovering and dust removingapparatus as described, the configuration and the method of theexemplary embodiments described above are not restrictively applied, butall or some of the respective exemplary embodiments may be combined witheach other so that the exemplary embodiments may be various modified.
